Nope, still haven't found a fix. Once my comfuser goes into Lock mode, the damn Windows picture comes up for a few seconds, but then the slideshow of my chosen pictures starts. I cannot find anywhere this Windows picture is, even in the registry.

Here after deleting the mentioned folders and assets on this thread it disappeared but now no matter how many times i choose a new picture, it always show the screen just with the plain theme color, no image uuuuuugggghhhhh.
